Yes, I know they are "self-sharpening."
I've had mine for a really long time. I'm guessing ten years or so. I got my money's worth, I think.
Lately, however, they are not cutting as well as they used to.
I've read you can cut through a few layers of foil to help sharpen them.
Has anyone successfully sharpened them - at home - without going to a professional? Or maybe I just ought to buy a new pair.
